thats a shame mate,but I know what you mean its quite difficult to buy a trance tune that your pleased with without listning to about 50 first.
I found that listning to other generes of music broadens my taste of music,for example my bro's a drum n bass Dj,and listning to some of the production and sounds d+b artists come out with is breathtaking.
Hard trance in my opinion needs to experiment much more,artists are too afraid of pushing the boundries just in case they kill the scene,but I reckon it will do the scene a favour.I wonder were we will stand in a few years??
